"The Expected Linux image was not found. Please check your NAND configuration" message is coming from: common/spl/spl_nand.c In practice this message seems coming from the fact that header of kernel image can't be identified from offset after executing: nand_spl_load_image(CONFIG_SYS_NAND_SPL_KERNEL_OFFS,,) So, something gets broken in while executing nand_spl_load_image. Perhaps CONFIG_SYS_NAND_SPL_KERNEL_OFFS value.
"Card did not respond to voltage select!" is coming from: drivers/mmc/mmc.c

One reason why I2C configuration is wrong in nand mode could be the fact that I have CONFIG_TI_I2C_BOARD_DETECT variable is undefined (because I do not have that eeprom). But it looks that do_board_detect runs enable_i2c0_pin_mux() that I do not run separately. On the other hand, that does not explain why mmc boot works.
Now I did this I2C0 configuration separately prior to running i2c_probe(). Nand boot went further now. However, main u-boot did not start properly. I got following messages Trying to boot from NAND The Expected Linux image was not found. Please check your NAND configuration. Trying to start u-boot now...

And game over.... So, it's not quite sure that voltage adjustments went through even though I2C did not complain anymore. There could be something wrong with nand settings, too. I need to check where these complaints are coming.
Thanks anyway for your comments, Matti
